Abstract
Superparamagnetic nanoparticles offer a wide range of applications in the emerging field of electronic devices. Recent developments have identified them as components for a new type of magnetoresistance sensor. A novel measuring method is used where increased field sensitivity is bought at the value of an inherent device noise. The proposed GMR sensor has many advantages, yet its output is feeble due to noise, and hence, there is a requirement for designing a signal conditioning circuit to improve the signal strength. The objective is to analyze the low concentration (sample) with a better signal conditioning circuit for the GMR sensor.
